Question 1 (1 point)
How are ketones different from aldehydes and different from esters in their
reactivity
Oketones are more reactive than aldehydes and less reactive than esters
O ketones are less reactive than aldehydes and less reactive than esters
Oketones are more reactive than aldehydes and more reactive than esters
O ketones are less reactive than aldehydes and more reactive than esters
Question 2 (1 point)
What will treatment of this compound with LiAIH4 accomplish versus DIBAL-H?
Reduction with excess LiAlH4 will give benzyl alcohol, using DIBAL-H will give
benzaldehyde
Reduction with excess DIBAL-H will give benzyl alcohol, using LiAIH4 will give
benzaldehyde
Reduction with a small amount of NaBH4 will give benzyl alcohol, using DIBAL-
H will give benzaldehyde
O
Reduction with a small amount of DIBAL-H will give benzyl alcohol, using
NaBH4 will give benzaldehyde

Question 3 (1 point) Which reaction scheme produces an aldehyde and why doesn't the other one work? 1. 50(312 o
2. LiAl(—0—tBu)3H
OH —>
B O Aworks, B doesn't because it produces an alcohol O B works, A doesn't because it produces an alcohol
0 Aworks, B doesn't because it is not strong enough to react O B works, A doesn't because it is not strong enough to react Question 4 (1 point) Select the reagent for the left reaction and the reagent for the right reaction: E10 —D- 30 O LiAlH4 is used for the left reaction and NaBH4 is used for the right reaction
0 NaBH4 is used for the left reaction and LiAlH4 is used for the right reaction
0 H2 is used for the left reaction and NaBH4 is used for the right reaction 0 NaBH4 is used for the left reaction and H2 is used for the right reaction
